UNITED STATES PATENT OFFICE.

LIPPMANN RAPHAEL, OF MEADVILLE, PENNSYLVANIA.

IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 217,239, dated July8,1879; application filed December 11, 1878.

To all whom it may concern:

Be it known that I, LIPPMANN RAPHAEL, of the city of Meadville, in thecounty of Oraw ford and State of Pennsylvania, have invented an ImprovedMeans for SupplyingOil to Lamps, of which the following is aspecification.

In the ordinary lamp the oil is supplied from a vessel below the burner,and when the vessel is full the best light is produced; but as the oilsinks away from the flame the light grows poorer. To remedy this is inpart the object of my invention, as well as to give greater safety fromexplosion.

The drawing shows a vertical half-section of the entire device, A beinga tank; B, a pipe connected with the bottom of A and terminating in thestop-cock O; D, a valve through the bottom of A, kept open by the springE when not closed by the screw-stem F. G is an open cup, into which theoil is dropped from the stop-cock; and H, an overflow-pipe leading fromG' into a pendent vessel, I. The cup G and disk M are rigidly connectedby the arm J. The pipe K conducts the oil from the cup G to thewick-tube L, which needs only to be long enough and wide enough to holdthe saturated Wick, and can be placed at any distance from the cup G.

The top of my wick-tube is just high enough to be on a level with thebottom of the overflow-pipe H, so as to have the oil at all times at thepoint that will give the best light.

I make the tank I to hold as much as the tank A, so that if through anyneglect the cock should be left open all the oil will be caught below.

The valve D is designed to regulate the 110w of oil for a full flame, atall times, to any given burner. The cock 0 is designed to check the fullflow when less light is needed.

I claim l. The cup G, overflow H, and tank I, substantially asdescribed, and for the purpose set forth.

2. The combination, in an oil-feeder to a lamp or lamps, of the tank A,pipe B, cock 0, valve D, cup Gr, pipe H, tank 1, bar J, pipe K, andwick-tube L, when made as described, and for the purpose specified.

LIPPMANN RAPHAEL.
